DIE FOR FORMENG PIKES.

SPECIFICATION forming part of Letters Patent No. 337,620, dated March 9, 1886.

Application filed October 28, 182 5. Serial No. 191.182. (No model] To all whom it may concern:

Be it known that I, ALBERT SANFORD, of Oshkosh, in the county of \rVinnebago and State of Wisconsin, have invented a certain new and Improved Die for Forming Pikes for Pike-Pole Pikes, Pevies, Pic-aroons, 820.; and I do hereby declare the tbllowing to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

My invention has for its object to provide improved dies for forming the pikes for pikepole pikes, pevy-pikes, picaroon-pikes, and other implements of like nature; and it consists in a certain improved construction, which will be presently described.

Heretofore pikes have been forged either by hand or by means of power-hammers with a single pair of dies for each portion-say one for the beveled pike and another for the round end or shank-and still another for reducing the round end. When a sufficient number of pike-blanks had the beveled end forged, the

dies on the hammer were changed and adj usted-an operation requiring much time and careful attention-and the blanks reheated and the next shape formed, then allowed to cool and the dies changed a third time, the blanks reheated, and the final finish given them. Each time the dies were changed they had to be adjusted both in the hammer and anvil very carefully, until they would come together and exactly register. All these operations and changes took a great deal of time, required a skilled workman to set the dies, besides re quiring the reheating of the blanks a number of times.

My invention does away with the removal and setting of the dies, and, furthermore, requires only one or at most two heats for the blanks.

In the accompanying drawings, Figure 1 represents a perspective view of thelower die; Fi 2, a side view of the dies together; Fig. 3, a view of an ordinary pike; Fig. 4, a view of a blank for a picaroonpike or pike-pole pike with ahook; and Fig. 5, aview ofa complete picaroon-pike.

Similar letters of reference in the several figures indicate the same parts.

The faces of the dies A and B are each provided, near one end, with the portion 0, beveled from front to rear, as shown, and with the half-round depressions l) and E, the latter slightly the smaller, as shown, and also with the depression F at the rear end, about the size of the depression 1' but provided with the screw-threadsf cut therein; and for making picaroou-pikes a depression, I, somewhat similar to 11),,butislightlysmaller, is employed for drawingsthe hook to a point. The lower die, B, is provided with a round perforation, G, in its face, for the purpose to be presently explained.

The lower die is secured to the anvil of the hammer and the upper one to the hammerhead, after the manner of ordinary dies, and so adjusted that the corresponding depressions shall register. ll", now, an ordinary pikeis to be formed, the blank is heated and placed in the beveled portion 0, and the head or point formed thereon by one or more blows of the hammer. Then it is reversed and the other end prcscnted,to form the shank, first t0 the die D, which rounds it somewhat, then to the die E, which reduces, and linall y to the die F, which forms a screw-thread thereon, and the operation is finished. A complete pike is the result, being accomplished at a single heat, or at most two of them.

If it is desired to make a picaroon-pike having a hook such as shown in Fig. 5, the forward end, h, of the blank H, in the form shown in lfijg. t, is presented to the die 0, which forms the beve1,as shown. Then the projection h is forced into the perforation G, which rounds it. Thenit is drawn to a pointin the die I. Then the blank is reversed and the shank formed in the dies D, E, and F in suec-ession, as before.

There are several important advantages gained by the use of my improved dies, the principal one of which is the time saved in forming the entire implement. Another advantage is the manner of placing the screwthread on the shank. llcrctolore the pikes were driven into the end of the wooden pole or handle; but as the poles are subjected to repeated wettings and dryings the ends are apt to expand and shrink, allowing the pike to pull out and become lost, but by the threads being formed thereon it cannot become loose and drop out, and if from any cause it should become broken it can be easily removed and a new one inserted.

Screw-threads are sometimes out upon the ends of pikes, but the operation is a tedious one and makes the pilies about one third more expensive; but they can be forged upon them by my improved dies at a very slight additional cost, and with the advantages above referred to.

I claim as my invention-- 1. The herein-describcd improved dies for forming pikes for pike -pole pikcs, pevics, &c., consisting oi the sections A and 15, having the beveled portion 0 and the half-ronnd depressions D and 1) and the threaded depressions F, subsl'anliall as described.

2. The herein described improved dies for forming pikes for pike-pole pikes, pevies, &c., consisting of the sections Aand B, having the beveled portions 0, the half-round depressions D and E, and the threaded depressions F, one of the sections having the perforation G, substantially as described.

3. The herein-described improved dies for forming pikes for pike-pole pikes, pevies, i

and picaroons, consisting of the sections A and 13, having the beveled portions G and halfronnd dc pressions D, E, and Land rhethreaded depressions F, one of said sections having the 30 perforation G, substantially as described.
